  • Simplified description (AI rewritten)
  • Technical description (Original)

This study is for adults aged 50 to 64 to test the safety and effectiveness of two vaccines, mRNA-1283 and mRNA-1273, which are designed to protect against COVID-19. Participants must be healthy and not have conditions that increase the risk of severe COVID-19. This means they will undergo a medical check-up, including a review of their medical history and some tests. People who had COVID-19 in the last 3 months or have had certain vaccines or treatments recently cannot join. They should not be sick or have a fever close to the study's start. Those who donated a lot of blood recently or took part in other studies can't participate either.

  • Duration: The study length is not specified, but participation includes screenings and monitoring.
  • Compensation: There may be compensation for participating in the study.
  • Risks: Possible risks include standard side effects of vaccines like soreness or mild flu-like symptoms.
